Ubuntu 26.04 LTS Beta Arrives:
Based on Linux 7.0 + GNOME 50 + Mesa 26.0
The public beta of Ubuntu’s next long-term support release lands today on schedule, shipping Linux 7.0, an exclusive Wayland-only GNOME 50 desktop, and a wave of Rust-rewritten system utilities — but two flavours quietly step back from LTS status.
Canonical released the public beta of Ubuntu 26.04 LTS “Resolute Raccoon” today, March 26, 2026 — exactly on schedule — opening the pre-release milestone to community testers worldwide. The official stable release remains fixed for April 23, 2026, giving developers and enthusiasts roughly four weeks to shake out any remaining rough edges.
The codename was chosen in honour of Steve Langasek, a former Debian and Ubuntu release manager who passed away in early 2025. “Resolute” reflects determination and unwavering commitment — fitting qualities for an LTS release that millions of systems will rely on for up to 15 years.
What’s New in the Beta
Ubuntu 26.04 LTS represents one of the most technically ambitious LTS cycles in recent memory, touching the kernel, desktop environment, graphics stack, system utilities, and package toolchain simultaneously.
Ships the latest RC of Linux 7.0 — a version-counter reset after 6.19, following the same tradition as the 5→6 transition. Adds Intel Nova Lake and AMD Zen 6 support, plus initial Qualcomm Snapdragon X2 coverage.
The GNOME session now runs exclusively on Wayland; the X11/Xorg GNOME session is gone. XWayland remains available for legacy X11 apps. Fractional scaling, autostart management, and VRR support are all improved.
The latest Mesa release brings improved NVIDIA Wayland performance and GPU compute improvements, benefiting both gamers and AI/ML workloads through enhanced Vulkan and OpenGL drivers.
Core system utilities have been ported to Rust for memory safety. Fallback options to traditional C utilities are retained for compatibility.
Full disk encryption backed by the system’s Trusted Platform Module is now a supported option at install time, with the ability to add, change, or remove a PIN after installation.
Resources (system monitor and task manager) and Showtime (video player) join the default app selection. The App Center consolidates software management, replacing the older Software & Updates utility.
AMD’s open-source GPU compute platform ships directly from Ubuntu’s repositories for the first time, making AI and HPC workloads on AMD GPUs a simple apt install rocm away.
glibc 2.42, Python 3.14 (now default), LLVM 21, GCC 15, Rust 1.93.1, OpenJDK 25, and post-quantum cryptography support out of the box round out the developer story.
“The beta image has largely eliminated the major defects that prevented installation and accurately reflects the expected functionality of the 26.04 LTS official release.”

Visual & UI Changes
On the surface, Resolute Raccoon sports a set of colourful new folder icons, a fully opaque Ubuntu Dock, and a fresh default wallpaper. A new boot spinner animation subtly refreshes the system startup experience. On the back end, kernel firmware packages have been split from one large bundle into 17 vendor-specific packages, reducing update bandwidth and freeing disk space for unneeded drivers.
Flavours: Beta Available, With Two Notable Exceptions
Beta builds of Ubuntu’s official flavours are available alongside the main release, each carrying LTS status — with two exceptions. Ubuntu MATE and Ubuntu Unity have both opted out of LTS designation for this cycle due to limited contributors. Both can still ship a 26.04 release; they simply will not commit to the extended five-year support period that LTS carries.
Flavours with LTS Beta Builds Available
- Kubuntu 26.04 — KDE Plasma 6.6
- Lubuntu 26.04 — LXQt 2.3.0 (retains X11 session)
- Xubuntu 26.04 — Xfce 4.20.1
- Ubuntu Budgie 26.04
- Ubuntu Cinnamon 26.04
- Ubuntu Studio 26.04
- Edubuntu 26.04
- Ubuntu Kylin 26.04
- Ubuntu MATE & Ubuntu Unity — non-LTS this cycle
System Requirements
The beta’s minimum hardware requirements are a 2 GHz dual-core processor, 6 GB of RAM, and 25 GB of free storage. Installation media can be loaded from a USB drive or DVD. An internet connection is optional for installation but recommended to access the full software catalogue.
Release Schedule
Should You Upgrade Now?
Beta builds are not intended for daily production use. If occasional crashes or rough edges are tolerable and you want to contribute to testing, installing now is worthwhile — updates applied through April 23 will bring the system to the full stable release in place.
For Ubuntu 24.04 LTS users on stable machines, the safer path is to wait for the 26.04.1 point release in August 2026, when the official upgrade route opens and months of post-launch fixes are bundled in. Ubuntu 24.04 LTS continues to receive security updates until April 2029, so there is no urgency to move immediately.
New projects built from scratch are well-suited to start on 26.04 once it stabilises — 15 years of potential support, native GPU compute via ROCm, and post-quantum cryptography provide a solid long-term foundation.
